How can I deal with someone that is acting like a 'diva'?

I think it's important when dealing with anyone we're having trouble getting along with to try to remember that everyone has a reason for their manner. Try to see things from a different perspective. It might be frustrating, or difficult to deal with someone acting this way, but that doesn't mean we can't do it. If it's getting really out of hand, it might be worth it to pull them aside and talk to them about it. They may not realize they're acting this way. Try to be understanding, and polite, There's no need to call them out and embarrass them in front of others. If that doesn't work, at least you know you made an attempt. If it's more than you can handle, there's no shame in backing yourself away from the situation that makes you uncomfortable.

What kind of relationship do you have with the "diva"? I would recommend setting boundaries with the person. First, identify what kind of interaction you want/are comfortable having with the individual and go from there.

From my experience "diva's" are people that have a big attitude. I have found that the best thing to do is to try to understand why they are acting up. Leaving them to it or calling them out may just make the situation much worse, so it is in my opinion best to listen and understand.

well, there simply isn't a legal way to just drop everything and not deal with them, and kick them out. but everyone has something that will intrigue them to stop their actions, just fascinate them.

Try having an open, honest conversation using "I" statements. Saying things like "I feel ______ when you _____" and maybe give them some loving suggestions about how they can improve their relationship with you.

There could be many different reasons why that person is acting in the way that they are. The best thing you can do is to try and stay calm, and recognize that you are bothered by their behavior. Maybe try addressing them directly, or going to an objective third party to explain the situation.

Give them a snickers... No honestly I guess you should try to talk with that person get him/her back to earth with honesty and in a calm manner.

You don't need to "deal" with anything unpleasant in life. Look at the situation, changes are that you can remove yourself from the situation, or limit exposure to the bare minimum; once a diva, always a diva (narcissist???); so, don't feed the monster and seek better company. Unless you want to self-sabotage your own life.

I think it would depend on how well you know this person. If you are good friends and the person is just having a moment, maybe let them have it. They may be trying to get something out of their system. If they are someone you do not know very well, this may just be their personality, or they may also be having a moment and just need some time to get out of it. I would suggest trying to discern why the person is acting this way, but if it is really bothering you, you may want to find a way to leave the conversation.

If someone is acting in this way, try to talk to them about how you feel in a non-confrontational way. Could you tell me more about how you are feeling?
